Former Utah Gov. Jon Huntsman

Now Ambassador to China, Republican Jon Huntsman previously served as governor of Utah and was once called a promising potential presidential candidate for 2012 by John McCain. Huntsman bucked the party line on global warming by first admitting that it exists and then by actually doing something about it — he signed up his state as a member of the Western Climate Initiative, a regional cap-and-trade agreement between seven western states and four Canadian provinces.
